Hello student,

In the question, it's mentioned that A body is originally at 80c and cools down to 60c in 20min.If the temperature of the air is 40c.

So, first DT/dt= 80-60/20=2.

So, after 40 minutes, 60-T/40= 2, so upon solving it seems that T= -20c.

So, the temperature of the body after 40mins is -20c.
